BOTTLE ULDSURE.

Application filed Iieeeinber To all whom it may concern.

Be it known that 1, JOHN O. Romans, a citizen of the United States, residing at Sawtelle, in the county of Los Angeles and State of California, have invented certain new and useful Improvements .in Bottle Closures, of which the following is a specification.

This invention relates to bottle closures, and it comprises a stopper or disk of cardboard or similar material adapted to be received in a groove formed in theneck of a bottle, said stopper being provided with openings, closure members arranged in said openings and resilient means for securing said stopper positively in position in the In the present invention I provide a stop per for milk bottles and the like having a. pair of openings arranged near opposite sides of the stopper, these openings being normally closed" by plugs or closure members which are readily removable for the purpose of pouring the contents of the bottle. In pouring, one of the openings serves as an outlet for the fluid in the bottle and the other as an inlet for air to replace the discharged liquid. This permits the contents of the bottle to be removed without removing the stopper.

I further provide means for preventing the stopper from dropping out of theneck of the bottle when the bottle is tilted to pour the liquid from one said means consisting of a resilient ring, preferably formed of metal, adapted to engage within the groove at the top of the bottle, The ends of the ring are provided with finger grips.

In the drawings, I have shown one embodiment of theinvention. In this showin igure 1 is a side elevation of the bottle, parts being shown in section, showing the invention applied,

is a plan view of theretaining vided with an under-cut groove 3 for the reception of a stopper. The usual stopper employed consists of a disk of cardboard, which is usually slightly larger than the upper portion of the groove 3 and. is adapt ed to be inserted therein. In the present invention it provide a stop per 4 consisting of the usual disk provided with openings 5 arranged near opposite sides of the stopper. The openings 5 are normally closed by closure members 6 having flanges 7 which engage the upper face of the support. The closure members 6 are held in position by frictional engagement with the edges of the openings 5. It will be obvious that the closure members 6 may be readily removed by inserting a sharp instrument beneath the flanges 7.

The foregoing description of the bottle to which-this invention relates applies to the type of milk bottle now in common use, as will be obvious. In the manufacture of these bottles it has been found that the diameter of the 0 )ening in the bottle varies slightly with di erent makes of bottles. lit Wlll be obvious, therefore, that if the stopper 4 were employed with a bottle having an openin of slightly larger diameter than is usua, there would be danger of the stopper becomin unseated from the groove 3.

in order to positively maintain the stopper in position while milk or other liquid is being poured from the bottle, I employ a retainingmember 8 preferably of a ring, as shown. The retaining ring is preferably formed of resilient metal and is provided upon opposite sides with swaged portions 9 which are preferably triangular in cross-section as clearly shown in Figure a, with their lower faces lying flat against the upper face of the stopper 4. The rin' 8 is preferably provided upon its ends wit upwardly extending portions 10 terminating in. ofit-set portions iiwhich are arranged parallin the form lel to and spaced from each other. The portions 11 of the ring serve as convenient finger pieces in applying the ring to the bottle and removing it therefrom. As shown, the

ring 8 is normally inserted within the groove.

- without danger of the stopper 4 becoming unseated. When it is desired to remove the stopper't'rom the bottle, the ring 8 may be removed by pressing inwardly upon the finger pieces l1 whereupon a hook or similar instrument can be inserted within one of the openings 5 and the stopper removed.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts ma be resorted to without departing from tie spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:

The combination with a bottle provided with a groove in its open end forming a shoulder and a disk mounted within the groove and resting upon the shoulder, of a resilient split wire ring provided upon its ends with finger grips, said ring being mounted againstsaul disk and being provided with outwardl swaged portions upon opposite sides provi ing sharpened edges to grip against the walls of the opening of the bottle above the shoulder therein.

In testimony whereof I affix my signature in presence of two witnesses.
